Compact unit

The LRS-16 is a managed SHDSL modem

concentrator presenting a cost-effective central-

site solution for point-to-point extension of E1

services in the Local Loop.

The concentrator can operate opposite 16

ASMi-52 SHDSL modems at remote locations,

providing E1 services over 2-wire lines. Each

one of the 16 fixed ports inside the LRS-16 can

have its own separate clocking.

Extended range

LRS-16 employs standard SHDSL TC-PAM 16

technology to extend the transmission range,

thus enabling carriers to reach more customers

at lower costs. The device uses an embedded

operation channel (EOC) for controlling and

monitoring the remote unit. The management

channel uses SHDSL overhead bits in compliance

with ITU-T G.991.2 requirements, and operates

without interfering with the data transmission.

Power supplies

LRS-16 operates with single or dual power

supplies. A power supply can be hot-swapped

(replaced) during operation, without affecting

system performance.

Management

The modem rack is managed by a UNIX-or

PC-based SNMP management system embedded

in the SHDSL rack. The user-friendly software is

GUI-based, and runs on PC/Windows

(RADview-PC) or HP OpenView (RADview-HPOV)

platforms. The SNMP management session can

be run over a 10BaseT Ethernet port.

Network management allows centralized control

of all LRS-16 hubs, modem ports and remote

modems in the network, including interface

configuration, connection setup, alarms, and

monitoring.

LRS-16 can also be managed from an ASCII

terminal that performs all SNMP functions

without a GUI interface.

Telnet allows terminal connection over any IP

network.

Diagnostics

LRS-16 has comprehensive diagnostics

capabilities that are activated from either the

ASCII terminal or from an SNMP management

tool. They include the following test options:

•

Local analog and remote digital loopbacks

•

SHDSL statistics collection for line

performance monitoring

•

E1 performance statistics per ITU-T G.706

requirements

LRS-16 is supplied in a 1U-high 19-inch

enclosure
